Nested
if
and else
statements can be used to choose
between several options.
But, sometimes it is inconvenient to use nested statements.
This chapter discusses
other statements that choose between
several options.
?
switch
statement
Neither of these statements
does anything that can't be done
with if
s and else
s.
But they are useful enough to know about,
and you will need to know them to use
programs written by other programmers.
Neither of these statements are part of the AP Computer Science test given to high school students in the US. For them, this entire chapter may be skipped. These statements are not used in the chapters that follow.
